FEED-WATER HEATER.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed September 12, 1913. Serial No. 789,430.

To all whom it may concern:

Be it known that I, EDWARD THOMAS TURNER, a citizen of the United States, and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in F eed-Water Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a construction of heater and purifier in which the water to be treated may be most effectively spread out into thin sheets throughout the steam portion of the apparatus bymeans of trays particularly adapted for the purpose, as hereinafter described.

A further object is to provide a large filter surface, a large storage and settling chamber with an efiicient oil separatorand a strong, rigid and neat construction in which the parts are so designed and constructed that the trays and filter may be readily and easily removed for cleaning, and ready and convenient access may be had at all times to every part of the apparatus.

The heater is designed to utilize exhaust steam for heating and purifying the water and the construction is arranged for use with heating systems whereby with suitable cut-out valves the oil separatorcan be utilized and the heater cut off at any time for examination or cleaning, without disturbing the supply to the heating system.

In the drawings, Figure 1 is a central longitudinal section of one embodiment of my invention, of rectangular vertical construction. Fig. 2 is a front elevation, partly in cross section, of the same. Fig. 3 is a perspective view of one of the trays. Fig. 4; is a central longitudinal section of another embodiment of the invention, comprising a horizontal cylindrical shell. Fig. 5 is a front elevation of same, partly in section.

In Figs. 1 and 2, I have illustrated my apparatus inclosed in a rectangular casing made up of sides 1, 1, bottom 3 and top 4, all suitably bolted and riveted together; while as illustrated in Figs. 1 and 5, the casing is constructed in cylindrical shape; other shapes to suit the requirements may also be provided as may be desired. In the rectangular shape, the side walls on the in- L side of the casing are provided with shelves 5, 5, projecting inwardly to form supports for the trays 6. The trays 6 are designed to spread out the water into thin sheets to more effectively bring it into contact with the exhaust steam with which the water is heated and purified. One of these trays is illustrated in perspective in Fig. 3, and con sists of a flat tray, with curved sides 7, 7, segmental in cross section, and a short distance within the two sides is provided with a vertical baffle partition 8, 8, for each side edge and parallel therewith. The ends 9, 9, of the tray are provided with supporting plates 10, 10, which are considerably longer than the width of the body of the tray so as to form lateral projections 12, 12.

The heater is provided with an opening sufliciently wide and closed by the large door 13, so that these trays can be slid into place within the heater and supported on the brackets 5, at each side. As many of the trays are employed as may be found desirable. In the construction illustrated, we have four rows, one above the other, with three trays in each row. The trays are slid into place crosswise of the length of the heater, and the supporting plates 10 abut up against each other so as to space apart the tray, and thus each tray automatically stops at its proper location. They can be read ily and easily slid into place through the wide open door, and they are in no way wedged or confined, so that they can be instantly removed from the heater, for cleaning or otherwise.

Located along the side walls of the heater in the lower portion thereof, is a set of shelves 14c, 14:, corresponding to the shelves 5, 5. These are designed for holding the filter grates 15, 15, which are perforated plates designed to hold between them suitable filtering material 16, such as excelsior, coke, hay and the like. These filter grates can be readily and easily slid into place through the wide opening in the front of the heater closed. by the door 17; and for cleaning or renewal, the grates and the filtering medium can be readily and easily withdrawn through the same opening.

In the upper portion of the heater, above the series of trays, the water inlet trough 18 is secured. The inlet water is supplied to the top of the heater through the inlet pipe 19 into the bottom of the trough 18,

and the trough is provided with a series of notches 20 along its side edge to allow the water to flow out of the trough and drop in smallstreams upon the uppermost trays; thence the water spreads out in the trays and runs over the sides and down along the bottom, dropping into the storage compartment where it passes through the filter and is-thoroughly filtered. The filtered water can be drawn off through the pump suction outlet 21 at the bottom olthe heater.

To prevent the water rising too high in the heater, I provide the trough 22 at the proper height, which trough is, in connection with the overflow pipe 23 preferably outside the heater, provided with a gooseneck trap. The water is heated by eXXhaust steam which is supplied through the exhaust inlet 24 at the back the apparatus. This exhaust inlet is formed with a downtu'rned elhow25 opening into an oil separator 26. The oil deposits in the bottom of the separator and the steam passes downwardly through the pipe 27 and the valve coupling 28 through the port 29 into the heater. The steam from the heater passes out through the exhaust outlet 30 in the top of the heater around the trays and the water trough, and the outlet of the steam is obstructed in its passage by the baflie plate 31, secured immediately below the outlet. The upper end of the oil separator 26 is provided with an exhaust steam outlet pipe 32 controlled by a suitable valve, not shown.

When it is desired to use the heater in connection with heating systems, the heater can be cut oil at any time by closing the cut-oli' valve controlled by the wheel 33 and the exhaust steam passes out to the heating systems through the outlet 32, thus enabling the heater to be cleaned without shutting oil the entire heating system. The oil from the oil separator is conveyed through a pipe 34 connected with the bottom thereof into the oil receiver 35, and thence by outlet pipe 36 to the point of use. A. float valve with ball float 37 is illustrated as controlling the flow of oil from the receiver. The oil separator is provided with a handhole and cover 88 for convenient access to the separator, for cleaning or otherwise;

In the uSe the apparatus, it will be understood that the exhaust steam passing into the heater, heats the water in the inlet trough practically to the boiling point, so that with the water spread out in the shallow trays, the deposits of lime and magnesia begin at once therein. As the water overflows the edge of the trays along the curved under sides, the deposits are retained on both the top and bottom surfaces, thus obtaining nearly twice the precipitating surfaces ordinarily obtained. I find the battles or partitions immediately within and lengthwise of the sides of the trays of great benefit in holding back the flow of water from the trays and in assisting precipitation. l/Vith these bailies, the water overflows the sides of the tray very slowly so that it does not drop ofl the side edges but runs down the curved sides to the bottom surface of the tray on the outside in a very thin sheet, giving ample time to the exhaust steam to precipitate the impurities. \Vithout the baffle plates there is likely to be enough current, swirling and vibration to carry over the edge of a' plain tray, small. spurts of water. The battle plates hold'back and stop practically allthis movement or flow oat water causing the slow, and regular movement desired. The trays are spaced apart by their abutting ends 10' so that the steam can pass readilyover and around each tray.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is r,

1. In a feed water heater, a series of trays for spreading out the water into thin sheets, each tray comprising a long shallow 'receptacle, with seg'mentally curved longitudinal sides, and bal'lie plates located within the tray parallel and adjacent to the sides to cause the water in overflowing to follow the curve of the sides on the outside.
